Most of this blog lives in the land of leadership frameworks, remote-work rituals, and technology that promises to streamline your life while quietly adding three new dashboards.

Today I want to talk about something radically unoptimized: postcards.

I love sending postcards. Always have.

When I travel, I still do the classic thing: I buy a stack of cards and send a few to people I know, the kind of friends and family members who will appreciate a quick hello and a picture of a place they may never visit. That part feels familiar, almost comforting. It is communication with a return address and a backstory.

But I also really enjoy sending postcards to people I have never met, and receiving them from strangers. That is where Postcrossing comes in.

The Postcrossing postcard exchange does something the internet promised and then forgot to deliver. It makes the world feel smaller without making it feel noisier. I do not get a feed. I get a mailbox. I do not get a recommendation engine. I get a real person, somewhere else, choosing a card, picking a stamp, and writing a few lines that exist only for me.

And because it is physical, it carries a different kind of meaning. The handwriting is unmistakably human. The stamps are little cultural artifacts. The card has traveled, sometimes slowly, sometimes with the bruises of its journey, like a tiny piece of slow travel arriving at my door.

In practice, it turns my mailbox into a small arrivals hall for stories, stamps, and handwriting from around the world. In spirit, it is a reminder that connection does not have to be instant to be real.

How the Postcrossing postcard exchange works

At its core, Postcrossing is a postcard exchange with one elegant rule: you send a postcard when you receive an address, and later someone else sends one to you.

1. You request an address on Postcrossing.
2. You mail a postcard to that person.
3. When your postcard is registered, your address becomes eligible to receive a postcard from another member.

It is simple enough to explain in one breath, and enjoyable enough that you keep doing it for years.

Why I like this postcard exchange

It is a community, but not the join our community kind

Postcrossing feels like a community without the pressure to perform, which is rare for anything described as a postcard exchange on the internet.

You do not have to post daily, build a personal brand, or master the subtle art of looking productive while holding a coffee.

You show up, you send a card, you receive a card. That is it. The bar is low, and the joy is high.

It is the world, in small rectangles.

There is something charmingly disproportionate about the whole thing. A postcard is tiny. The planet is not. And yet these little cards arrive from places I have never visited, written in handwriting I will never reproduce, carrying stamps that look like miniature museum exhibits.

It is a reminder that the world is not just headlines and hot takes. It is also someone in another country choosing a postcard, writing a message, and briefly thinking of a stranger.

The surprise is real.

Email delivers certainty. Notifications deliver urgency. The Postcrossing postcard exchange delivers mystery.

Some days, you check the mailbox, and it is flyers and existential dread. And then, suddenly, a postcard. Just a cheerful snapshot of someone else’s corner of the world.

It is slow, and that is the point

Postcards are the slow travel of communication.

They do not arrive instantly. They drift. They take the scenic route. They remind you that not everything needs to be real-time. There is a whole category of joy that lives after anticipation.

Also, and this is important, they make patience feel like a lifestyle choice rather than a system error.

20 years of Postcrossing, and a very official kind of applause

The platform has been doing this for 20 years now. Postcrossing started in 2005, which in internet time is roughly three geological eras.

The anniversary has been a small victory lap for the idea that slow still works. A few postal services even marked the occasion by issuing Postcrossing-themed stamps. Belgium joined in too. bpost released a 20 years of Postcrossing stamp sheet, which made my inner philatelist, a person I did not know I contained, sit up very straight.

How I send postcards in the countries I visit

Whenever I travel, I turn into someone with a mission: find a post office, buy stamps, and locate a mailbox that looks official.

I love choosing cards that actually match where I am. A museum card from a museum. A seaside card from the seaside. A card featuring a local landmark that I definitely mispronounced while asking for directions.

If you enjoy sending postcards, a Postcrossing postcard exchange gives you a reason to do so with intent, to an audience that genuinely wants to receive them.

There is also a sneaky benefit. It makes me pay attention.

When you know you will be sending a postcard, you start noticing postcard-worthy things: colors, buildings, street scenes, the particular way a city holds its light. It is tourism with a bit more intention and a bit less quick to take a photo, so I can forget it later.

How Postcrossing became my Power BI example

I teach Business Analytics with Power BI at Karel de Grote College University in Antwerp, and one of the most complex parts of teaching data is this: people think data is either tedious or intimidating.

So I include the Postcrossing postcard exchange data. A postcard exchange is perfect teaching material because it is personal, global, and measurable without turning into corporate jargon.

With Postcrossing statistics, you can explore:

• Geography: where do my cards go, and where do they come from?
• Time: how long do cards travel, and which routes are fastest or slowest?
• Patterns: Are some countries more frequent than others, and do my habits change when I travel?
• Seasonality: Do I send more in summer, and do I receive more around holidays?

Suddenly, dashboards are not abstract. They are about something specific and human: a network of tiny connections moving through real space and real time. It is also a quiet lesson in a very modern idea. Your best data project often starts with something you actually care about. Because when the topic is yours, your hobby, your curiosity, your strange affection for postal systems, you keep exploring long after the assignment is graded.

A gentle nudge: if you are not in a top-five country, we need you even more

If you spend any time in Postcrossing, you will notice a practical truth: some countries are postcard superpowers. That is wonderful. Thank you, prolific postcard people. Truly.

But there is also a balancing act behind the scenes. To keep exchanges fair and flowing, the system often relies on the same high-participation countries again and again. The model stays stable, but the variety can get a bit repetitive.

Which is where you come in.

If you live outside the top five Postcrossing countries (Germany, the USA, Russia, the Netherlands, and Finland), joining is not just another hobby. It is a small act of global diversification. You add new routes, stamps, handwriting styles, and perspectives. You increase the chance that someone, somewhere, opens their mailbox and thinks: Oh wow, I have never received a card from there.

If you have been waiting for a sign to join a postcard exchange, consider this your officially unofficial sign.

If you are considering Postcrossing, here is what I learned by actually doing it

I started with the basics. A standard postcard and a pen were enough. No special stationery, no calligraphy era, no artisanal ink sourced from a distant monastery.

I learned quickly that you do not have to be poetic. The cards I enjoy most are rarely perfect. They are warm, specific, and human. Friendly beats fancy every time.

I also learned that you do not have to be extroverted. This is introvert-friendly socializing at its best: connection at arm’s length, with postage, and with plenty of time to think before you write.

And yes, you will develop opinions about stamps. I did. It happens to everyone. One day, you are buying postage; the next, you are comparing designs like a sommelier evaluating notes of citrus and oak.

One more thing I learned the slightly anxious way: you get to choose the rhythm. Early on, every time a card I had sent was registered, I felt a tiny internal alarm that said: send the next one, immediately, or the postcard gods will be disappointed. They will not. These days, I send when I feel like it, sometimes one, sometimes a small batch. Postcrossing is a postcard exchange, not a cardio program.

Quick FAQ about the Postcrossing postcard exchange

One last thing

We spend so much time communicating at high speed that we forget what slower communication feels like. The Postcrossing postcard exchange brings back a form of connection that is small, physical, and pleasantly inefficient. It is a reminder that community can be quiet, that global can be personal, and that the world is still full of strangers willing to write a few kind sentences on a piece of cardboard and send it to you. If that sounds appealing, consider signing up, especially if you are in a country that does not show up on everyone’s dashboards all the time.

Help the map look a little more interesting.

And give someone, somewhere, a reason to check their mailbox with hope.
